NAME

gcore — get core images of running process

SYNOPSIS

gcore

[-c corename] pid [pid ...]

DESCRIPTION

gcore creates a core image of the specified processes suitable for use with gdb(1). By default, the core is written to the file “<progname>.core”, where “<progname>” is the program name of the process corresponding to the pid that is given on the command line. This filename can be changed by supplying the -c corename argument, or setting “proc.<pid>.corename” with sysctl(8).

FILES

<progname>.core

The core image.

SEE ALSO

gdb(1), sysctl(8)

HISTORY

gcore appeared in 4.2BSD, disappeared in NetBSD 1.2, and reappeared in NetBSD 2.0.

BUGS

The process is not stopped while the core file is generated, so it might not be consistent.
